Eaton PDG12XHM79E – Frequently Asked Questions
1) Will the Eaton PDG12XHM79E handle mechanism fit any Power Defense breaker, or only certain frames?
Frame 1 only. The PDG12XHM79E is built for PD1 Global molded case circuit breakers in Eaton's Power Defense series, and it will not mount on larger Power Defense frames. Check the frame designation on the breaker before ordering.
2) Does this Eaton handle mechanism meet NFPA 79 for an emergency disconnect on machinery?
It's an emergency NFPA79-compliant shaft handle, supplied in the red-and-yellow color scheme NFPA 79 expects for an emergency disconnect so operators can find it fast on a machine panel. It also carries CSA certification and is RoHS compliant.
3) What voltage can the Power Defense PDG12XHM79E handle mechanism be used at?
Up to 600 V maximum. That covers the usual 480Y/277 V and 600 V industrial control panel systems, so it suits standard machine-tool and panelboard work.
4) How much space do I need in the enclosure for this Eaton handle mechanism?
Allow for a body measuring 37 mm wide, 63 mm deep and 53.2 mm high. That is the mechanism itself; the operating shaft and door handle run out to whatever depth your enclosure requires, so lay out door clearance around those footprint numbers.
5) Can I add the PDG12XHM79E to a Power Defense breaker already installed in a panel?
Yes, it is an accessory that mounts to an existing Frame 1 PD1 Global Power Defense breaker to convert it into a door-operated emergency disconnect. Common uses are machine control panel retrofits and upgrades where an NFPA 79 shutoff has to be added to equipment already in service.
6) What exactly is a circuit breaker handle mechanism, and do I still need a breaker?
A handle mechanism is the rotary operator assembly only, not a breaker. It bolts onto the breaker and transfers the on/off action to a shaft and external handle so the breaker can be operated from outside the enclosure door. You supply the Frame 1 PD1 Global Power Defense breaker separately.
7) Is the Eaton PDG12XHM79E acceptable for a panel being built for the Canadian market?
It is CSA certified, which is the listing Canadian inspectors look for on a panel accessory, and it is RoHS compliant for export builds.
